Just letting people know.
I had to put my kegs in room tempature while finishing my keezer.
One had a metallic taste. After awhile the beer tasted normal. Doing some research, found out it my be over carb'ed.
Also, when making a keezer, buy the eva (gun safe) packs. It sucks up moisture and can be reused by plugging it in an outlet to heat up and dry.
hope this helps someone.
